To: all whom it may concern Be it known that 1,: JOHN EDWARD filar-SON,- afcitizen of the United States-residing in Philadelphia,Pennsylvania, have k1n- 5 lvented Y certain new and useful Improvementsin Attachment Devices for Electric Fixtures, oik which the following 1sa specification. c *Y Various forms .of electric connecting dellov'vices yhave beenfmade prior to my'present y invention for the vpurposeof enabln'igther attachment of 'electrically -operativeaappara- Atus toreceive electric: current from electric lighting fixtures withoutvinterfering with the use of i the fixtures for lighting purposes ,orwithout d'es'troyingthe ornamental char- ^acterof the fixture. Certainot these yprior art devices include 'socket portions. which are secured,as by solderfto the main shells ornamental parts for closing theentrance .to the sockets when the .latter are not-.desired for useforfattachmentpurposes. 'I'Others of sa.icl1pi'ior art devicesfhaveornamental vparts which hang or depend `entirely outside of the mainbody of thenixture, saidornamental parts including :the attachmentsockets. y

One object of my kpresent invention kisto provide an improvedattachmentdevice, for

theabove mentioned purpose, which can bemade to readily fit within themain body portion of an electrlcxture and which can vbe quickly andfirmly secured in place; the

that parts thereof ywill hold or bind the sections of the fixture bodyltogether and will also support the "socket vproper independently of theelectric-conduit Wires so that no weight or strain will be imposed onsaid Wires during` 1 ment purposes.

Another object isV to make the parts of my invention 'of Vaaneat anddurable con-l struction land so that ?it canbe quickly and easilyinstalled in a properfmanner by a workman .Without requiringgreat skill.

The llowersection l11 isopen bottom andisprovidedwitha surroundin skirt flange 16 which telescopically litswithin the conlines :ofthe top edge portion 13 and 'abuts the `ledge'll'v asv clearly shown in Figurel. l The bottom I17 of the-lower'.'body'section li is provided with a yhole 18 whiohis prei:-

fr suspensionrloop 2l hasa base 22 providing a'holeQZ-f The hole 23 hasan' enlarged internally screw threadedV `portion 24 into f which isscrewed-the `upper end portionot 'an externally screw threaded tube 25.Thel tube 25 extends throughth'ehole I19 into the space within thebody-10fandat'jitslowerl end is screwed i'ntofthe'upperv end ota turnbuckleor hicke'y'26, l A i a ,portion' 27 which may. berpmadep-ginf the formot fa casing tot meta-l l"as fillustrated `:and whichhas a part 2S'ofgreater diameter Y @10,0 My improved VVattachmentc' device includes 18into the space within the body l0. The iiange 28 serves to limit theupward movement of the casing by abutting the outer surface .of thebottom 17 of the body i0.

An electric connecting' structure or inner socket 29 is located withinthe contines of the socket casing 27 and, in the form of the structureillustrated, includes a metallic screw threaded portion 30. A shell 3lof insulating material is interposed between the casing 27 and the screwthreaded portion 30 of the socket 29. The lower end of the shell 3lpreferably depends belov.T the lower ends of the portion 29 and casing27 and the .upper end of the insulating shell 8l preferably abutsashoulder such as the shoulder 32 of the body portion 38 of theconnecting structure 29. The shell 3l can be forced into place and beheld by friction so as not to fall, or if desired this shell can beotherwise suitably secured to either the casing or structure 29.

The top of the connecting structure 29 includes a clamp 34 and portions35 which are held by the clamp to the outer threads of the lower end ofa nipple 86 at a position within the casing 27. The nipple 36 extendsupwardly through a hole 37 in the top of the casing. Lock nuts 38 and 39on the nipple 36 are located adjacent opposite surfaces of the top ofthe casing 27 and secure the nipple to the casing 27. rIhe upper end ofthe nipple is screwed into the lower end of the hickey 26.

It will be noted that by providing a structure as described andillustrated, the casing 27 serves to support the lower section ll of thefixture body l0, and since the casing is connected to the base of theloop 2l through the medium of the nipple 36, hickey 26 and tube 25, thesections of the body will be held and clamped together.

The main electric conduit wire 4() leads into the fixture through thehole 23, tube 25 and hickey 26, and branch electric conduit wires 4l and42 are connected to the main conduit 40 and lead through the hickey 26and nipple 36 into the casing 27 where they are electrically connectedto the Structure 29 and respectively electrify the portion 3() and a.contact member 43, said portion 30 and member 48 being electricallyinsulated from each other.

which screws intothe portion 30. A screw 4T leads through the plug 46andthrough a cap 48 into a tapped opening in a knob 49. The plug, c'p, andknob are keyed or otherwise sec-ure together against relative rotation.The cap 48 preferably has a recess 50 into which the lower ends of the:casing 2 7 and shell 31 extend, said recess being surrounded by aflange 5l which ab'uts the lower surface of the iixture body l() whenthe plug is screwed in so that all parts of the device can be concealedand the cap 48 and knob 49 of said closure simulates a porti-on of thebody 10.

If it is desired to make an electric connection for any electricalapparatus, such for example as for an electric vacuum cleaner,percolator, fan, toaster or the like, the closure canbe removed byremoving 'the plug 46, and then the connecting plug on the conduit orextension wire of the apparatus can be inserted in the socket so thatsaid latter plug makes electric contact wit-h the portion 3() andcontact 43.

In Figures 5 and 6, I have illustrated at 27 a casing or portion whichcan be made of stamped, cut or pressed metal 0r other suitable materialwhich can be used in lieu of the casing 27 above described. Owing to theopen or cage-like character of the p0rtion 2,7Ct the wires 4l and 42 forthe socket need not enter through the nipple but can lead to the innersocket through the spaces between the parts 52. The parts 52 haveflanges 28'EL for abutment with the bottom of the fixture body in thesame manner as the flange 28 of the casing 27.

In Figure 7 is illustrated a form of casing 27b substantially similar tothe casing 27 with the exception that it is provided with apertures 53through which the socket-connecting wires can pass if it is not desiredto pass them through the nipple.

It will be understood' that if the nipple is not used for a passage forthe socketconnecting wires, said nipple if desired can be made solidinstead of tubular. Furthermore while I have described the inner socketportion connected to the nipple by the clamp 34 it will be understoodthat any other suitable connecting means may be employed and the innersocket can be of any of the usual or well known forms of construction.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is 1.
